Abstract

Universal Soil Loss Equation (USLE) and Geographical Information Systems are two spatial soil erosion analysis models because both have a spatial context. As an important factor, soil erodibility is crucial in determining soil erosion, with C-organic significantly influencing the K value. The main aim of this study is to characterize soil erodibility and soil loss based on spatial simulation of the effects of soil C-organic in a GIS environment. Research findings indicated that by simulating within a GIS environment, C-organic can affect soil erodibility and erosion. Low C-organic levels can increase soil erodibility, while high C-organic levels can decrease it. A reduction in C-organic by 10%, 20%, and 30% will increase K by 1.10%, 1.17%, and 1.21%, respectively. Conversely, adding 10%, 20%, and 30% C-organic will decrease K by 1.12%, 1.27%, and 1.46%, respectively. A 10%, 20%, and 30% increase in C-organic can reduce soil loss by 1.2%, 1.3%, and 1.5%, while a reduction in C-organic will increase soil loss by 1.1%, 1.2%, and 1.3%, respectively. A low K value indicates slight erosion, while a high K value suggests high erosion. Continuous C-organic and properly managing vegetation are necessary to maintain and improve soil quality.

Abstract

Stevia plant, as an alternative to sugarcane, is a plant that is susceptible to drought. The growth and yield of the stevia plant is highly dependent on the availability of sufficient water and nutrients. To get optimal crop yields is necessary to pay attention to the water needs of the stevia-growing media. The right intensity of watering and using organic fertilizers are efforts that can be done to prevent drought. This study aimed to determine the effect of vermicompost and water application intervals on the growth and yield of stevia plants. A divided plot design was used in this study with 12 treatment combinations with three replications. The basic pattern of completely randomized design (CRD) consists of 2 factors with three replications. The main plot is the interval of giving water (I), namely I1 = 1 day, once, I2 = once every 2 days, I3 = once every 3 days and Subplots, namely the dose of vermicompost, consist of 4 levels, namely V0 = 0 tons/ha, V1 = 5 tons /ha, V2 = 10 tons/ha, V3 = 15 tons/ha. The data were analyzed using analysis of variance. The significant difference between treatments is determined using Duncan's Multiple Distance Test at 5%. The best watering interval is the interval of giving once every three days and vermicompost 5 tons/ha.

Abstract

Jember Regency is one of the national food storage areas. One of the most important resources in cultivating food crops is water which comes from rainfall. The existence of rainfall data is very important in planning and implementing agricultural activities. Limited rainfall data is the main problem for agricultural planning. One solution to this problem is to utilize rainfall data from CHIRPS (Climate Hazards Group Infrared Precipitation Station). The use of CHIRPS data is still biased data, so bias correction is needed to measure the level of accuracy of CHIRPS data for estimating rainfall in an area. Bias correction is carried out using two methods, namely multiple linear regression and power regression. The correction results show that the multiple linear regression method is able to produce monthly rainfall that is close to observations with an RMSE value of 3.9 and a coefficient of determination of 0.99. Temporally, the peak of the rainy season in Jember Regency occurs in December while the dry season is in August. In the rainy season (December-January and February) Jember Regency's rainfall is around 300-500 mm/month and in the dry season (June-July-August) it is in the range of 50-200 mm/month. Spatially, the northern part of Jember, especially Sumberbaru, Bangsalsari and Tanggul subdistricts, is wetter than the Jember Regency area as a whole. The southern part of Jember, especially those close to the coast, has lower rainfall than other regions. In the dry season, rainfall in this region is less than 20 mm/month.

Abstract

One of the causes of low productivity in cucumber plants is due to low soil quality due to low organic matter content and high sandy soil mixture. Considering this, it is necessary to try to improve it. So, there is a need for research that examines the addition of organic matter and combines sandy media with paddy soil.This research took place in Pecoro Village, Jember Regency from May 2022 to July 2022. The research method was in the form of a Completely Randomized Design with the first treatment, namely the addition of baglog waste compost and cow manure (K1); baglog waste compost and goat manure (K2); and compost baglog waste and chicken manure (K3). While the second treatment is sandy planting media consisting of: sand 100% (M0); 75% sand + 25% paddy soil (M1); 50% sand + 50% paddy soil (M2); and 25% sand + 75% paddy soil (M3). The observed variables included plant height, total fruit weight, fruit unit weight, fruit length and fruit diameter which were tested by means of variance and Duncan's Multiple Range test.The results showed that the treatment of compost, sandy planting media, and their interactions had a significant effect on the observed variables. The recommendations given based on the results of the analysis for cucumber cultivation are the need to add organic matter such as compost mixed with baglog waste and manure from cow, goat and chicken manure with a ratio of 25% sandy planting medium to 75% paddy soil.

Abstract

Declining soil fertility caused by the continuous use of chemical fertilizers has encouraged the development of sustainable and environmentally friendly nutrient management strategies. Compost tea, a liquid extract derived from mature compost, has gained attention due to its potential to supply readily available nutrients and beneficial microorganisms. This study aimed to evaluate the compost tea production process and assess the effects of aerated compost tea (ACT) and non-aerated compost tea (NACT) at different application concentrations on the early growth of maize (Zea mays L.). The experiment was conducted under controlled conditions in November 2025 using maize as the test plant. Compost tea was prepared by extracting mature compost in water at a ratio of 1:5, with aeration applied for ACT and without aeration for NACT over a three-day fermentation period. Treatments consisted of ACT and NACT applied at concentrations of 30 ml and 60 ml, along with a control. Plant growth parameters, including plant height and root length, were observed during the early growth phase (2–7 days after planting). The results showed that compost tea application significantly affected maize growth during the early growth stage (P < 0.05). Aerated compost tea generally produced better growth responses than non-aerated compost tea, particularly at lower concentrations. The ACT treatment at 30 ml resulted in the highest plant height and root length, while higher concentrations, especially NACT at 60 ml, tended to suppress plant growth. These findings indicate that compost tea primarily functions as an early growth stimulant and that excessive application may reduce its effectiveness. In conclusion, aerated compost tea at low concentrations is more effective in promoting early maize growth than non-aerated compost tea. Proper optimization of compost tea concentration and application strategy is essential to maximize its benefits within sustainable agricultural systems.
